    Im trying to set up Cloudflare for my server but im having some issues,Let me start off by saying im no expert and just a hobbits so im limited in what I know exactly. I can get it working on my main sites but I keep getting problems trying to get Cloudflare to work for my mail client at and for my control panel at ive pinned it down to the fact that my urls are ending in ports.
    Ive tried setting up page rules to redirect https:// to http:// because it seems Cloudflare keeps trying to direct to HTTPS,
    Ive tired to set up subdomains and and then use origin rules to set Cloudflare to connect to origin on ports 8080 and 8081 with no success. Im at a loss right now with what I really should be doing to get Cloudflare to work for my server.

    Any guidance would be much appreciated!

    Default CF settings normally work out of box in my experience.

    I guess you can not use CF proxy for any service besides ports 80 and 443. So you must turn off the proxy for the A-record of the server hostname and use this hostname to access ISPConfg GUI and webmail client.

    The only thing I can get working is cloudflare for DNS providing. As soon as I try to mask my IP I run into issues where I can’t load the mail client and only being able to access my control panel through my servers IP address

    A    @    IP_ADDRESS    600 seconds       
    A    cp    IP_ADDRESS    600 seconds       
    A    mail    IP_ADDRESS    600 seconds       
    NS    @    1 Hour   
    Can't delete
    Can't edit
    NS    @    1 Hour   
    Can't delete
    Can't edit
    CNAME    www    1 Hour       
    CNAME    _domainconnect    1 Hour       
    SOA    @    Primary nameserver:    1 Hour       
    MX    @ (Priority: 10)    1 Hour       
    TXT    @    v=spf1 mx -all
    My DNS record looks like this now, but on Cloudflare the only difference was the addition of cloudflares name servers for NS

    Cloudflare does not support HTTPS for port 8080 (they use HTTP on that port only, see post from @pyte) and tey do not support port 8081 at all. So you can not use Cloudflare proxy to access ISPConfig on port 8080 or webmail on port 8081 at all. Plus CloudFlare proxies web traffic only, as far as I know, so you can not use their proxy for services like email (imap/pop3/smtp) when accessing it with a mail client.

    What you can do is that you change the ISPConfig GUI port and webmail port to a port supported by CloudFlare, if you do not want to disable CloudFlare proxy. Change port 8080 to 8880 in the file /etc/apache2/sites-available/ispconfig.vhost and port 8081 to 8443 in /etc/apache2/sites-available/apps.vhost and restart the web server.
